CYCLE-LAMP.

SPECIFICATION forming part of Letters Patent No. 373,911, dated November 29, 1887.

Application filed February 5, 1887. Serial No. 226,66l.

To all whom it may concern:

v Be it known that I, HAROLD SERRELL, residing at Plainfleld, in the county ofUnion and State of. New Jersey, have invented certain new and useful Improvements in Cycle-Lamps; and I do declare the following to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, which form a part of this specification.

' My invention relates to an improvement in cycle-lamps, the object being to produce a lamp burning with a bright clear flame and protected against accidental extinguishment.

With these ends in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a View of the lam-p in vertical section through the side lights. Fig. 2 isa similar view through the head-light and reflector, with the oil-fount removed. Fig. 3 is a view in transverse section on the line :0 w of Fig.1,with the oil-fount removed. Fig. 4. is a similar view on the line y y of the same figure. Fig. 5 is alike View on the line 2 z of the same figure; and Fig. 6 is a broken view in perspective of the fouiit,showing its draft-guard.

As herein shown, the lamp-frame A is pro vided at its lower end with an inner shell open in front for the reception and removal of the fount B, and comprising the bottom plate, 0, the side plates, D and E, and the rear plate, J. The said plate 0 is imperforate and supports the fount. It extends to the rear of the frame A; but between its side'edges and the sides of the frame are spaces, as shown. The side plates, D and E, are provided at their forward edges with flanges F F, which are closed into the frame, and at their upper edges with perforated flanges G G, also closed into the frame, the "plate E being cut away, as at H, to receive the, wick-spindle I of the wickraiser applied to the oil-fount. It will thus be seen that these side plates are imperforate, except at their upper ends. The rear plate,

J, is-perforated at K, and provided at its upper edge with a perforated flange, L, which is located in part under the reflector N. The lower edges of the side plates, D and E, respectively, join the opposite side edges of the (No model.)

Under the construction described side flues, I

O O, and a rear flue, I, are formed between the side and rear plates and the said frame, and deliver air into the flame chamber Q through the described perforations of the plates and in part at the level of the flame. The said side flues, O 0, take air directly from an airchamber, R, between the' side edges of the plate 0 and the frame, while the rear flue, P, takes air from the side flues and only from them, being cut off from the air-chamber R by the rear end of the said plate 0. The said air-chamber is located below the bottom plate, 0, and between the same and a horizontal parallel perforated plate, S, located at the lower end of the frame A. All imperforate plate, T, located below the plate S and forming a guard therefor, is also secured to the lower end of the frame,with which it is connected at its rear and forward edges, its ends being open, as at U U, to admit air to the perforated plate S, as shown.

A draft-guard, V, consisting of an upright flat plate, is mounted upon two bent arms, W W,secured to the top of the fount, in position to bring the guard in front of the opening X, made in the frame A to receive the wickspindle, which occupies the rear end of the slot, the draft-guard being in front of it.

Air enters the lamp at U U, and, passing through the perforations of the plate S,enters the air-chamber R, from which it flows between the sides of the frame A and the adjacent edges of the plateO into the flues O O,

where it is diffused, a part of it issuing into the flame'chamber at about the level of the flame through the perforations of the flanges G G of the plates D and E, and a part passing around the rear edges of such plates and into the flue P, whence it is delivered into the flame-chamber th rough the perforations in the body and flange of such plate.

The whole lower part of the lamp becomes heated from the flame, and the air, passing through the flues, herein provided for, and

hence between heated metallic surfaces, becomes considerably raised in temperature before it reaches the flame-chamber.

By heating the air, as described, it is better prepared for combustion, the flame is not chilled, and a more brilliantlight is obtained, with a more perfect combustion of the illuminant. The heated surfaces also produce a current, insuring a continuous supply of air to the flame, and thus making its free burning largely independent of outside atmospheric conditions. Finally, under the described con struction the force of the air entering the lamp is so broken that the accidental dropping of it, and the rush of air caused by wind or fast riding, will not create a partial vacuum and put out the light.

The imperforate guard plate T may, if desired, be dispensed with, as it is not essential to the successful operation of the lamp; and I would have it understood that I do not limit myself to the exact construction and arrangement of parts herein shown and described, but hold myself at liberty to makesuch changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a cycle-lamp, the combination, with a lamp-frame, ofa shell located in the lower part ofsuch frame, made open in frontand including side, rear, and bottom plates,thesideplates being imperforate except at their upper ends,aud the bottom plate being also imperforate, and flnes communicating with the flame-chamber of thelamp,being formed between thelamp-frame and the said side and rear plates and taking air at the lower ends of the former, and a current breaker located below such shell and breaking the air before it enters the said fines, substantially as set forth.

2. In a cycle-lamp, the combination, with the frame thereof,of ashelllocatedin thelower part of such frame, adapted to receive the oilfonnt,provided with openings at or near its up per end, and comprising side and rear plates and an imperforate bottom plate, side and rear flues being formed between the respectiveplates and thelamp-frame for the passage of air which enters the flame-chamber through the openings in the shell, the rear flue communicating with and taking air only from the side flues, substantially as set forth.

3. In a cycle-lamp, the combination, with the frame thereof, of a shell located in thelower part of such frame,adaptcd to receive the fonnt and comprising an imperforate bottom plate and perforated side and rear plates, side and rear flues communicating with and discharging air into the flame-chamber, being formed between such plates and the lamp-frame, and an air-chamber located below the said bottom plate, the side ilues communicating with and taking air from such chamber and the rear flue communicating with and taking air from the side flues and being cut off from the said airchamber, substantially as set forth.

4. In a cycle-lamp, the combination, with a lamp-frame having the lower ends of its side walls imperforate,ofashell located in the lower part of such frame and including an imperforate bottom plate and side and rear plates, and a perforated plate located below the imperferate bottom plate of the shell, with an air-chamber between it and the same, flues communicating with the flame-chamber of the lamp, being formed between the side and rear plates of the shell and the lamp-frame and taking air from the said air-chamber, substantially as set forth.

5. In a cycle-lamp, the combination, with a lamp-frame, of a shell including an imperferate bottom plate extending to the rear wall of the lamp-frame, side plates joining the edges of such bottom plate and connected with the frame at their upper ends, and a rear plate connected at its upper end with the rear wall of the lamp-frame, at its lower end with the bottom plate at a point forward of the rear end thereof and at its sides with the rear ends of the side plates, fines communicating with the flame-chamber of the lamp, being formed between such shell and thelamp-frame andtakingair atthelower endsofthe sideplates of the former, and a current-breaker located below thebottom plate of the shell for breaking the air before it enters such ilues, substantially as set forth.

In testimony whereofl have signed thisspecification in the presence of two subscribing witnesses.

HAROLD SERRELL.
